2452/53-SL Diaphragm in 2453J and bolt pattern?

[emilime75]

Hey, all. Wondering if anyone knows if the D8R2452-SL or D8R2453-SL diaphragms will work in a 2453J? If yes to both, is there any reason to choose the 53-Sl over the 52-SL? The 53 is $35 dollars more per diaphragm and I need 4, maybe 5.

Also, does anyone know what bolt pattern a 2453J is?

The 2453 comes with an integrated back cap. The 2452 does not. Do a google search for images. H and J are interchangeable.
